Hi Keith,
There is no fuse between the battery and the voltage regulator. As for
gauge of the wire, it needs to be pretty heavy stuff. I'm not exactly
sure what the stock gauge is, but I would use 10 gauge.

I have a single speedo, some sort of Veglia (not stock). Has black face, white numbers, black ring around the glass and a tripometer. Has 4 idiot lights. I took the housing off to check the lights situation as well as to polish the housing. What I found and what happened is interesting and confusing. The parking lamp bulb was burned out, also found that the oil bulb was out. When I took one of the known good bulbs and put it in the parking lamp slot, it worked when I grounded it to it's housing. When I took a known good bulb and put it in the oil lamp and grounded it to the same housing, it did not. Hmmmmm. I pulled out the meter, checked for continuity from the lamp to the oil pressure switch (disconnected the wire from the switch), good, got connection. Hooked the wire back to the switch, turned the key on, and got no voltage showing at the lamp. Go figure. At this point, I took the speedo out and housing off, then messed around again for awhile. Next thing I noticed, nothing worked. Uh Oh, something must have shorted out, but what and why? BTW, what is the single wire going to the speedo for? Can I assume it was a ground wire and that was what caused my short? Took the cafe fairing off, removed the headlight, and found a blown 10 amp fuse where the ignition switch hot lead (red) connects to the fuse panel. Changed it and took a chance to see if all was well and nada, no lights no nothin. Got the meter out again, no 12 volts present anywhere on the fuse panel, OK, the battery juice ain't makin it up to the fuse panel, lets go see whats up at the battery end. Low and behold, I found an inline fuse connecting the positive battery terminal to the voltage regulator. Now: 1. Is this supposed to be there? Looks like something the previous owner wired up. 2. If it is supposed to be there, what size fuse is supposed to be in there? When I opened up this inline fuse, I noticed the holder was not a good design. Part of the fuse (the metal cap) got jammed in one end, the other came out without a problem. So now I looking at a metal end with glass cylinder and half of the metal fuse, the other end stuck (and it aint coming out) in the other half of this inline fuse holder. Unfortunately, the stuck end has the amperage rating on it, so I have no idea what size this fuse is, looks like perhaps a 30 amper. So now my last questions are: 1. See question 1 above, if this is not supposed to be here, I'll splice the line together. What guage wire should be used from the battery to the VR? 2. What could have caused both this fuse and the 10 amp fuse in the headlamp to blow? I did notice last eve when putting the rear wheel back on (more polishing last eve!) that something in the area of the VR sparked when the wheel bumped it on it's way back in (remember I have no fender on the bike). Perhaps that blew out the 10A fuse on the headlight? Thanx for any help! Keith Ruff 70 Cafe Racer Ambo Manahawkin, NJ Paul P. Linn wrote:
